Hypertension prevalence, awareness, treatment, and control, in male South Asian immigrants in the United Arab Emirates: a cross-sectional study

Abstract

BackgroundSouth Asian males constitute the largest proportion of the United Arab Emirates (UAE) population. Minimal data is available on the prevalence of hypertension among South Asian immigrants in the UAE. We determined the prevalence, associated factors, awareness, treatment, and control of hypertension among male South Asian immigrants from India, Pakistan and Bangladesh residing in the UAE.MethodsWe recruited a representative sample (n = 1375; 76.4 % participation rate) of South Asian adult (≥18 years) immigrant males, including Indian (n = 433), Pakistani (n = 383) and Bangladeshi (n = 559) nationalities in Al Ain, UAE (January-June 2012). Blood pressure, height, body mass, waist and hip circumference data were obtained using standard protocols. Information related to socio-demographics, lifestyle factors, history of diagnosis and treatment of hypertension was collected through a pilot-tested adapted version of the STEPS instrument, developed by the World Health Organization for the measurement of non-communicable disease risk factors at the country level .ResultsMean age of participants was 34.0 years (95 % confidence interval (CI): 33.4, 34.5 years) and the overall prevalence of hypertension was 30.5 % (95 % CI 28.0, 32.8). In this study, 62 % of study participants had never had their blood pressure measured. Over three quarters (76 %) of the sample classified as hypertensive were not aware of their condition. Less than half (48.5 %) of the sample that were aware of their hypertension reported using antihypertensive medication and only 8.3 % had their hypertension under control (<140/90 mmHg). Hypertensive participants were more likely to be overweight (adjusted odds ratio (AOR) = 1.43; 95 % CI 1.01, 2.01); obese (AOR = 2.49; 95 % CI: 1.51, 4.10); have central obesity (AOR = 2.01; 95 % CI 1.37, 2.92); have a family history of hypertension (AOR = 1.51; 95 % CI 1.05, 2.17); and were less likely to walk 30 minutes daily (AOR = 1.79; 95 % CI 1.24, 2.60).ConclusionsThe prevalence of hypertension in a representative sample of young male South Asian immigrants living in the UAE was relatively high. However, the awareness, treatment, and control of hypertension within this population were very low. Strategies are urgently needed to improve the awareness and control of hypertension in this large population of migrant workers in the UAE.

Prevalence of Diabetes among Migrant Women and Duration of Residence in the United Arab Emirates: A Cross Sectional Study

“…Our findings provide further support for the worrying observation that the Healthy Migrant Effect or “immigrant health advantage” is temporary. On arrival, immigrants have a better health status than the native population but their health declines as their stay increases [36]. There are limited data on the behaviors that explain acculturation and its effects on BMI and diabetes prevalence.…”

Pharmacological basis for the medicinal use of polyherbal formulation and its ingredients in cardiovascular disorders using rodents

“…Pakistan is one of the South Asian countries where around 18 million people at the age of fifteen and above are living with hypertension. Out of these, around 70% population is even unaware about the disease status, while only 3% successfully control blood pressure with regular medication [4–6]. Multiple antihypertensive therapeutic agents are available to combat this deadly disorder, however, their high cost and life-long use of the medication along with associated multiple adverse effects ultimately results in patient unaffordability and poor-compliance [7].…”

Is Migration Affecting Prevalence, Awareness, Treatment and Control of Hypertension of Men in Kerala, India?

“…This might be the reason for higher prevalence of overweight among migrants. Higher prevalence of overweight, central obesity and hypertension was reported in an earlier study among young South Asian male migrant population in the United Arab Emirates [30].…”
